Abstract: In today's interconnected and digitally driven era, Device-to-Device (D2D) communication has emerged as a transformative paradigm, enabling direct and efficient interactions between nearby devices with or without traditional network infrastructure. This research introduces a novel communication protocol that autonomously facilitates D2D communication in network-constrained environments, maximizing node engagement and ensuring reliable data transmission while addressing the inherent challenges faced by existing Medium Access Control (MAC) protocols, such as Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). The study specifically focuses on developing a protocol that enables real-time information sharing among neighboring nodes without network assistance. To evaluate the protocol's performance, comprehensive simulations were conducted using MATLAB,assessing its effectiveness in increasing the number of active nodes and reducing collision probability. The results demonstrate that the proposed protocol significantly decreases interference while enhancing data throughput and energy efficiency, achieving a 15% increase in active node pairs and a notable 4% reduction in collision probability. By minimizing contention overhead and optimizing data transmission, the protocol effectively lowers latency, ensuring reliable communication in environments lackingnetwork support. Furthermore, it conserves energy by reducing idle listening, thereby extending battery life and promoting sustainable wireless communication systems. This research provides a robust solution to enhance D2D communication in isolated environments, paving the way for more resilient wireless ecosystems.
